9.1.3. Data transfer mode

Three data transfer modes are available; stream, auto printing and manual printing.

Stream mode

Transmits data in sync with the display update rate. If

the indicator can not catch up with the update rate

because of the baud rate, the transmission is paused

until the next updating.

The transmitted data is the same as what is being

displayed. Data that is not displayed is never

transmitted.

Auto printing mode

Transmits data once only when the weight value with

5 d or greater is stable.

For another transmission, the weight value must fall

below 5 d once.

Manual printing mode

Transmits data when the F key that is assigned to

Manual print command is pressed or a command is

sent from the CC-Link master station.
